Urnula Claparede & Lachmann, 1859 (ref. ID; 2013)
Class Kinetofragminophora: Subclass Suctoria: Order Suctorida: Suborder Exogenina (ref. ID; 2013)

[ref. ID; 2013]
Body approximately oval situated within, but not filling, an irregularly cup-shaped lorica. The posterior region of the lorica is constricted into a stalk-like attachment point which is usually bent to one side. There is an apical rounded or triangular aperture through which 1 or 2 (but up to 5) long active non-capitate tentacles protrude. The apical end of the lorica is narrower than the central region. The nucleus is oval and centrally situated. There are one or more contractile vacuoles. The organism is usually reported to be found growing on the stalks of Epistylis plicatilis.
